Cheshire invites B.J to the flat so they could catch up and Sherlock wants to get away from them. Bucky is more than happy to take a tour of London, so when he hears that Loki is in town with toy versions of the Avengers, he and Sherlock are on the case. Sherlock would have gotten John, but since John hasn't had enough sleep since the baby was born, he decided not to annoy John. It was only an hour after they left did the girls realize they had left. Cheshire was being patched up by B.J and her headache was subsiding thanks to some medicine. "Oh, did I tell you? Juggernaut is scared of me." B.J said while she stitched Cheshire's arm. "That big dumb ass? How'd you.. Never mind." Cheshire said looking around. B.J caught on and saw a little Captain America action figure on the coffee table. "Okay, I know we both look up at the Avengers massively, but why do you have a toy?" asked B.J. Cheshire saw the toy and picked it up. It scared her when it started moving. "Bucky J., where's your dad?" it asked. B.J kicked it across the room while Cheshire went to put it under a tea cup. "Okay, I need to stop reading those Supernatural books." B.J sighed. Cheshire laid a book over the cup and took a seat back on the couch with B.J. "That was unusual. Think I could dissect it?" Cheshire asked. B.J shook her head and got back to fixing Cheshire up. Cheshire returned the favor by disinfecting B.J's arm. B.J had to clean the wound at least once a day even though it was scabbing. Because she was always fighting, sometimes it would open up and need cleaning. "Cut and burned. Geez, whoever did this to her is colder than me." Cheshire thought as she wrapped t up in a clean white wrapping. "Thanks. Normally my dad helps me out with it." B.J said as she uncaged the toy and picked it up. "Weird, it has a body temperature." Cheshire took it and stuffed it in her police box backpack. B.J had the same backpack and they rolled their eyes at each other when they saw the backpacks. "It's what you get for getting me hooked on Doctor Who comics, Chess." B.J used as an excuse. Cheshire made a face and they went to take on London.
They went to Angelo's and had dinner there while they talked about the toy in Cheshire's backpack. "Okay, I have a hypothesis, but it's farfetched." B.J proposed while they left the café. Cheshire took out the toy and set it on a bench. Both sat down next to it and looked at it. "I heard Loki was around and the Avengers aren't in New York. That's another reason why I'm in London. What if Loki turned Cap into a toy?" B.J proposed holding the toy. It suddenly started moving. Cheshire took it from B.J and looked at the blinking eyes. "Well, time to go find a god." she said setting the toy down. Cap started moving around and rubbed his eyes. "B.J, where is your dad?" he asked looking up at her. B.J shrugged and rubbed her arm. "How'd you get turned into a toy?" B.J asked as she picked him up. Steve sighed and explained what Loki did. "Smooth." Cheshire said when she heard the story. "Look. We need to find Loki and get him to change everyone back to normal." he said inside B.J's backpack. B.J and Cheshire may have the same backpack, but B.J has buttons on it. That was the only way they could tell which backpack was which. Steve has seen B.J with her backpack so he knew which one to hide it. "Don't get lost, Captain Rogers." B.J instructed as she and Cheshire started looking in possible areas for Loki.
Meanwhile, Bucky and Sherlock were stuck as dogs and were in the flat. "What now, genius?" Bucky growled. Sherlock was thinking while he paced around. "We can only talk for a limited time per hour. Loki is somewhere in London, at least we know that. I suggest we go towards the upper-class area and search." Sherlock said. It was close to midnight when the girls finally came back. B.J and Cheshire saw the dogs and looked at each other. B.J saw one with a metal arm and the unmistakable red star. "Dad?" she called. The dog wagged his tail and pulled his pointed ears flat across his head. "Loki?" Cheshire asked the dog with ice eyes. She knew her brother when she saw him. Sherlock huffed and got on the couch. B.J took out toy Steve and told Bucky what happened. "So, you watch him." B.J said standing Steve next to Bucky. Cheshire dismantled Sherlock's unused dinosaur of a monitor and started making something to track Loki down. B.J helped and made one for herself. She saw something green on Bucky's paw and took it. "Ha, it works." B.J smiled as she got up. Cheshire's worked too and both started going out. "Oi, you two stay here." Cheshire ordered. B.J ended up letting her dad follow them as they went around to find Loki. Bucky attacked a mugger and Sherlock chased him down the street with the girls getting them to stop. "I see a pet store." Cheshire knew where B.J was going with this and followed along. B.J watched the dogs as Cheshire paid for two collars and two leashes. B.J leashed her dad up ad they started walking. "This is beyond weird." B.J said. Her dad was feeling the same way until he smelled something. He and Sherlock led the girls to a man with pale skin like Sherlock's and emerald eyes. He was talking to a shorter man and a boy. Cheshire knew the boy and swallowed her rage. Andy and Jim were taking to Loki. B.J gave Cheshire the leash she held and switched backpacks. "Captain America escaped, but as promised, I have the others." Loki said handing them a box. "Oh, I have Cap, Loki." B.J called from the alley. She showed Cheshire's backpack and smiled. Loki sighed and looked at Jim. The Irish man motioned for Loki to get her. "Cheshire?" Andy called. Cheshire started walking to B.J and stood there. "That dick-face?" B.J asked. Cheshire glared at said boy and nodded. Sherlock raised his hackles and growled. Bucky did the same. Steve crawled out of the backpack and jumped in the green ray that was aimed at the girls. A blonde dog was in his place. "What's with you and dogs Loki?" B.J asked as she picked up a trashcan lid and threw it.
Both girls dodged another green blast. "I don't know. Just bored, is all." Loki answered. Jim swooned. "A madman after my own heart." Jim said with a twisted smile. Cheshire took a trashcan and threw it at Andy and went behind the dumpster B.J hid behind. Sherlock growled and started charging towards Andy. Andy started running and ran across traffic that Sherlock could not. Jim kicked Sherlock, but Steve and Bucky tackled him as they growled. A small yelp sounded and Cheshire was a dog. Loki was beyond B.J's league and he managed to change her into a dog. "That one girl with the wrapping on her arm had a good point. Why dogs?" Andy asked after crossing the street back to where his uncle was with Loki. Loki sighed with a shrug. "Why not. Honestly, I'm bored and this was a boring job, Jim Moriarty. I will see you when I find that Norn Stone you and I agreed to use to take over a few continents." Loki said before disappearing in his green mist. Jim and Andy left in a hurry to escape the angry dogs in a car where Seb saw the whole thing. B.J's wrapping came loose and fell off her arm. Cheshire saw how self-conscious she was about it and wasn't sure what she could do. "You two okay?" Bucky asked. "Wait, we can talk?" B.J asked. Bucky sat down and ripped Sherlock's collar off. "For a limited time per hour." Sherlock answered. Steve ripped Bucky's collar off. Cheshire laid down and yawned. "Well this sucks." Cheshire sighed. Both girls looked like puppies and Bucky was able to pick B.J up by the scruff of her neck. Sherlock did the same and they walked to John's place. Mrs. Hudson would've fainted if they went back to Baker Street. Sherlock tried to talk when they finally got there, but his voice was a bark. It wasn't time for them to speak. They went to an alley and waited there. B.J was bored and very shy about her arm and made sure that she hid it, so no one starred at her. John was just about to go to the store before he left for work when something caught his eyes. A blonde dog, four brown dogs, one with a metal arm with a star and two with ice eyes. "Oh, hello, John." Sherlock greeted. John rubbed his eyes and squinted. Was he really that tired? "Blame Loki." Cheshire called walking up to him. "Loki, the bloke from the New York alien thing a few years ago?" John asked. Sherlock nodded and sat in front of John. For the second time that week, John called in and said he wasn't able to work and explained to Mary why there were five dogs in their living room. B.J wandered off somewhere in the house and looked for anything to cover her arm.
Mary was relieved to get out of the house and get to work because the dog people were now John's problem. "Have anything to eat?" B.J asked with a medical kit in her mouth. John was a little confused about the medical kit until he saw her arm. "Uh, yeah. Want me to wrap that up for you?" he asked taking the kit from her. "Yeah. Don't ask." she said sitting down. Bucky sat in the kitchen and watched John. He didn't trust easily and John could tell. After wrapping B.J up, he went to the fridge to take out any left overs in there. B.J sniffed at the Styrofoam and heard Cheshire coming up behind her. Both girls sniffed and ate what they wanted. "This is so weird being dogs." B.J said between mouthfuls of a steak. Cheshire didn't answer as she ate some lo mien and saw B.J wanting to go outside. John let her out, but instantly regretted it when she ran off down the street. "I'm going after Loki!" she shouted back. Cheshire had a look on her face and ran before Sherlock could grab her. "Oi!" Johns started running after them and he last three went with him and did what he said to do. The girls had wits and they knew what to do. Sherlock wasn't a super soldier and stayed closed to John as Bucky and Steve looked around. The two came back. They lost the girls in the hurry of early London traffic.
